The Super Sled travels with an initial kinetic energy of 3369 J horizontally and to theright along a frictionless flat surface, initially at a height of zero (initial gravitationalpotential energy = 0). The driver briefly engages the rocket over a distance (Ax) of2.000 m, pushing the sled with a force of 400.0 N over that distance. The rocket isthen turned off. The sled then goes up an inclined surface with a rough surface. Thecoefficient of kinetic friction on the incline is uk. At the top of the incline, the sledreaches a height h = 1.500 m above the ground where the surface becomes flat andfrictionless again. The sled (including the rocket and driver) has a total mass of 87.00kg.(Notes: assume that g = 9.810 m/s² , and that the mass of fuel used by the rocket isnegligible.

Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”

Question

The Super Sled travels with an initial kinetic energy of 3369 J horizontally and to the
right along a frictionless flat surface, initially at a height of zero (initial gravitational
potential energy = 0). The driver briefly engages the rocket over a distance (Ax) of
2.000 m, pushing the sled with a force of 400.0 N over that distance. The rocket is
then turned off. The sled then goes up an inclined surface with a rough surface. The
coefficient of kinetic friction on the incline is uk. At the top of the incline, the sled
reaches a height h = 1.500 m above the ground where the surface becomes flat and
frictionless again. The sled (including the rocket and driver) has a total mass of 87.00
kg.
(Notes: assume that g = 9.810 m/s² , and that the mass of fuel used by the rocket is
negligible. Do not use scientific notation).
